Abbreviation
Explanation
Control unit,
control board
The drive contains two ZCU control units. One controls the line-side converter, the other the
motor-side converter.
As standard, the external I/O control signals are connected to the control unit, or optional I/O
extensions mounted on it.
Drive Frequency converter for controlling AC motors. The drive consists of the line-side converter
and motor-side converter connected together by the DC link.
In this manual, the term refers to the ACS880-17 as a whole.
Drive control
unit
The control unit which controls the drive through the motor-side converter. The user control
interface to the drive.
In this manual, the term refers to the motor-side converter control unit of the drive

Frame (size) Relates to the construction type of the component in question. For example, several drive
types with different power ratings may have the same basic construction, and a frame size is
used in reference to all those drive types.
To determine the frame size of a drive type, see the rating tables in chapter Technical data.
FSO-12,
FSO-21
Optional functional safety module
IGBT Insulated gate bipolar transistor; a voltage-controlled semiconductor type widely used in
drives due to their easy controllability and high switching frequency.
Line-side
converter
The part of the drive that converts AC to DC for the motor. Includes an LCL filter.
The line-side converter of the ACS880-17 is also capable of feeding regenerative energy
back into the electrical power network.
Motor-side
converter
The part of the drive that converts DC to AC for the motor. The motor-side converter is also
capable of feeding energy from a decelerating motor into the DC link.
I/O Input/Output
RFI Radio-frequency interference
